This is because Safari 2 used to only support GET and POST. It seems
there are (old?) proxies and firewalls out there that only accepts
GETs and POSTs.
The workaround is to call the protected constructor through the use of
a subclass; e.g. using an anonymous subclass (if you do PUTs at
several places in your code, consider re-using a named subclass
instead of creating an anonymous one at each call-point):
RequestBuilder rb = new RequestBuilder("PUT", url) { }

We're using a POST request with an X-HTTP-Method-Override request
header, à la GData, for our PUTs. This was pretty straightforward for
us as we have a helper class that creates the RequestBuilders and
hides the details (this is used to catch 401s and show a "you've been
logged out, please sign in again" screen, and add authentication
credentials to all requests). In our case, the RequestBuilder is not
exposed at all outside this helper class, because we do not have a
need to tweak the request headers on a by-request basis; but it could
easily be done without much change to our code.
So, yes we're using "REST with GWT with success and minimal coding".
(note that we do not use Struts2 on the server side)
